1 General Overview
The PAG (PAG = Porsche AG) Transmitter RKE (Remote Keyless Entry) + Kessy produced
by Continental AG is an electronic car key for remote control access via button press in
Porsche motor vehicles, with the additional function of bidirectional access authorization (via
LF communication). With this system, the key no longer has to be actively activated by button
press in order to open the vehicle.
There are several variants with different radio frequencies, depending on the destination
country and market.
The PAG-Transmitter RKE + Kessy consists of the populated PCB integrated in the lower
housing, manufactured by Continental Temic Automotive (Phils.) Inc., Baksakan Road, FTI
Estate Taguig, 1630 Manila, Philippines and is delivered to company Huf, Hülsbeck & Fürst
GmbH & Co. KG, Steeger Straße 17 (Huf Hauptfirmensitz), 52551 Velbert, Germany.
The PCBs are then assembled with other plastic components in order to complete the PAG
Transmitter and delivered to Porsche AG.
